  • CORROSION RESISTANT STAINLESS STEEL - The only broad-market muffler with 100% stainless-steel construction that delivers longer life versus aluminized mufflers while an internal drainage system reduces moisture collection
  • EASY TO INSTALL - Direct-fit bolt-on replacement solution with OE-style hangers, brackets and pipe routings for easy installation and doesn't require specialized fabrication and/or welding
  • BUILT TO LAST - Internal partitions and mechanically joined tubes allow expansion and contraction during temperature changes to minimize distortion while spun-locked heads and OE-style spot welds provide structural stability and longer service life
  • PREMIUM ACOUSTIC CONTROL - OE-style louvered tubes lower noise levels while OE-style domed heads help reduce radiated noise for premium factory-style sound quality compared to straight perforated tubes
  • DESIGN VALIDATED - Acoustic and flow tested for quality OE-style sound you can count on

Fit easily into a 2014 Subaru Legacy 2.5L with trailer hitch, and it does the job of quieting the engine sound though not as well as the OEM muffler did. However, the muffler is only made of 409 "stainless steel" which very much does rust, the welds are poorly finished and not protected against rusting, and the rear tip of the exhaust pipe is rolled inwards which traps condensed moisture from the exhaust and impedes the airflow. Not the greatest design or execution but a reasonable value for the money. I hope it resists rusting out longer than I fear it will.

Used this to replace a 2015 Subaru Legacy muffler. While it did fit, it was a good bit smaller. I also bought the metal gasket and the holes did not line up with holes in the Subaru pipe. It was easy enough to drill new holes in the gasket though. Muffler sound is deeper than OE in my case.

OEM was rusted out. OEM cost three times as much. This one is stainless - it won't rust out and buying here was $80 less than the auto parts store. Great deal.

Replaces the rusted out muffler perfectly. Perfect fit and mounts. Only need to purchase the gasket in between.
